The utility model discloses a motorcycle rear braking rod which comprises a positioning pin shaft sleeve and a pedal. The utility model is characterized in that a four-bending rod which is orderly upward bent, rightward slightly and crossly bent, frontward longitudinal bent and rightward crossly bent towards the pedal and passes by an exhaust pipe is arranged between the positioning pin shaft sleeve and the pedal. The first upward bend of the motorcycle rear braking rod avoids the exhaust pipe so that the exhaust pipe is positioned below the motorcycle rear braking rod. Thus when in rear brake, any parts of the braking rod do not contact the exhaust pipe. When a motorcycle runs on a rugged road, the motorcycle can not contact the ground no matter how to brake because the exhaust pipe firstly contacts the ground. As a result, the problem of a braking accident caused by rugged mountain roads is solved. Moreover, the rod has good interchangeability with the original braking rod and is suitable for the motorcycle which often runs on the rugged road.
